In November 1776, Allan comes to Malva's grave and confesses to
Later, after Claire has returned to the Ridge, she is confessor to Allan Christie, who explains that he was the one that fathered Malva's child, and then murdered her.
Allan's father Tom later took the fall and falsely confessed to killing Malva in the hopes of ending Claire's trial.
We find out who did it in A Breath of Snow and Ashes, but it takes some time. Claire is arrested for murder, but Tom learns the truth in the end. It was Allan who did it. It turns out Allan sexually abused and raped Malva, and he is the father of the child.
Jamie does not sleep with Malva in Outlander
The story comes out over the course of A Breath of Snow and Ashes. Malva makes her story about Jamie being the father of her unborn baby convincing.
Jamie denies having slept with her, but the damage to his and to Claire's reputation is done—and the bond between the Frasers and Malva is severed, until just a few weeks later, when Claire finds Malva murdered in the garden. “It's like the peak of the tragedy, and it's so visceral.
Claire eventually realizes that Malva is lying because she knows her husband well enough. Tom seems to question Malva's story. You can see it in his face that he's trying to figure out if this story is true. And then there are the reactions at the funeral when Allan refuses to let Claire carry the baby's coffin out.
Malva, before her death, tells him that she made them sick. She'd collected parts of the dead Sin Eater and poisoned Claire and Tom. She wanted to get to Jamie, and getting Claire out of the way was the only way to do that.
Malva was first introduced at the beginning of the season as a new resident of the Ridge who admired Claire's medical skills. Behind her admiration was a darker side of blackmail, betraying Claire's trust, and stalking. She falsely claimed Jamie was the father of her unborn child.
After attending to Claire 24 hours a day for almost a week, Malva and housekeeper Mrs Bug (Sarah Collier) decided to cut her hair off, thinking it would help reduce Claire's temperature. Having to rock a much shorter hairdo for her character, Balfe, revealed she “wasn't a big fan,” of the shorter look.
But Tom isn't guilty either — eventually Allan Christie confesses to Claire that he is both the father of his sister's child and that he murdered her to stop her from telling anyone.
He had left it too late, though – driving a commissary wagon, he was waylaid by a government troop of Campbells, and they arrested him. Tom was first sent to Berwick Prison, then transferred to Ardsmuir Prison in 1752.
Malva Christie might have only been introduced in Outlander Season 6, but she has a central role in the drama. The daughter of Tom Christie, she is both naive and sinister, and many Outlander fans have struggled to work out her true intentions.
The preacher had inadvertently fallen in love with Claire and couldn't let her die, particularly for a crime he knew she could never commit. Sadly, it wasn't looking good for the time traveller who was last seen trying to perform an unsuccessful caesarean to save Malva's unborn child.
Some of the residents of Fraser's Ridge believe that the child's condition is a punishment for his parents' sins, and gossip runs rampant in the backcountry. Fergus is ashamed of not being able to protect his family properly and provide for them, and makes an attempt to end his own life, but Jamie stops him in time.
In the TV series, we get to see how Malva knows all about Jamie's scars. She spies on Claire and Jamie when they're in the barn, which is going to lead to all of his scars on show. The TV show gave us this scene so that it would clear up questions later on.
She is eager to learn more about medicine and surgery. Throughout the episode, she worked with Claire and learned how to use the ether. Then she questioned Claire about her book and what Claire writes in there.
Lizzie says that she did attempt to talk to her the day Malva died, but the door to the surgery was locked. Those knocks were what Claire heard in her hallucination before she found Malva's body. This knowledge should transform her way of thinking, but Lionel appears in the surgery.
“For Claire, the ether is not addictive in itself, but the feeling it gives you is. The idea of putting yourself to sleep and not having to deal with any of these feelings she's having inside, that is something Claire will become addicted to.”
Fans are convinced Outlander heroine Claire will be poisoned by Malva after she was seen slicing off a finger of the dead Sin Eater (David Gant) who was introduced in episode two.
Traditionally, a sin eater was a person (usually a man) who was paid to eat bread that sat upon the corpse at a funeral. Thought to have soaked up their sins, when eaten by the sin eater, it absolves the dead of their sins leaving them free to enter heaven unburdened.
In a shocking turn of events, Outlander season 6, episode 6 saw Claire's apprentice Malva accuse Jamie of infidelity, claiming her unborn child is Jamie's, but the aftermath forgets one critical detail from Outlander season 3.
It turns out Ian and Malva did sleep together. It was only the once, but we all know how these things work.
Jamie: "Claire, it was you. It's always been you, and it always will be. Get into bed and put the candle out.
Fitz, who washes her hair and admires her purty skin. Claire is moved to confess the truth to Mrs. Fitz: Her husband isn't dead. He hasn't been born yet.
